I have lower back pain as well as my side and abdomen. the pain comes and goes and i habe also been trying to get pregnant for 5 months with no luck. could i be infertile, could the pain be a symptom?

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Wish you good health!
